Hakase! I have an upcoming fossil test at school, what kind of fossils should I remember?
The coverage of the test seems to be fossils in the junior high school field.
There are only a limited number of fossils in the junior high school fossil exam, and not many of them!
In this article, we will discuss 11 selected fossils in the junior high school range.
Fossils are always learned in junior high school.
It is important to remember at least the representative fossils that appear frequently in the textbook.
In this article, let’s learn about selected fossils that frequently appear in the middle school range with guinea pigs!
Facies fossils and Index fossils
First, let’s review Facies fossils and Index fossils.
I know that a facies fossil is one that shows the environment at the time the strata were deposited, and an index fossil is one that shows the age at which the strata were deposited!
Selected fossils〈Facies fossils〉
I will now describe four selected fossils of the facies fossils.
The corals are fossils indicating that they were deposited in warm, shallow waters, Asari clams in shallow seas, Freshwater clams in lakes and estuaries, and the beech in slightly colder regions of the temperate zone!
Makes sense, given the environment they currently inhabit!
Selected fossils〈Index fossils〉
Next are seven selected fossils of the Index fossils.
Fossils that indicate they were deposited during the Paleozoic include trilobites and Fusulinida, Ammonites and Dinosaur during the Mesozoic, and Mammoths, Naumann elephants, and Vicarias during the Cenozoic!
Should I remember what it says in ( ) below?
For middle school studies, the broad framework of the Paleozoic, Mesozoic, and Cenozoic eras is fine. If you want to know more about geological eras, or if you are studying basic geology in high school, remember!
In this article, I introduced 11 selected fossils, including facies and index fossils. All of them are very frequent.
I’ll review well and get a perfect score on the test!
Hakase! Thank you for teaching me!
Thank you for reading to the end!
